The upper the number, the more heat the furnace can wring from each therm of fuel.

Furnaces have become more vitality-efficient over time. A gas furnace made in the early 1970s typically has an AFUE rating of about 65 %. The bottom efficiency allowed by law for brand new gasoline furnaces is 78 percent, and a few new fashions achieve ninety seven p.c, near-complete efficiency.

Of the greater than 20 gas furnace brands we rated, Trane and Payne stood out as the most dependable, earning Excellent scores for predicted reliability. Six different manufacturers earned Excellent reliability scores.
